RUBBER BOOT.

arncrrrcArIoN forming part of Letters Patent No. 303,220, dared August 5, 1884.

To @ZZ whom it may concern.-

Be it known that i, FRANCIS FLYNN, of Woonsoclcea in the county of Providence and State of Rhode Island, have invented certain new and useful. Improvements in Rubber Boots, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification. Y

This invention has reference to the class of rubber boots used by quarrymen, miners, and others, Whose occupation compels them to wall: among sharp-edged stones and quartz, liable to cut the soles and uppers of the rubber boots as ordinarily eonstructed.y

' rPhe invention consists in providing a rubber boot or shoe with a tap or double sole projecting beyond the main sole, either all around the boot or shoe or in front of the 2O heel only, as will be more fully set forth hereinafter.

Rubber bootsy have heretofore been coustructed to iit them for particular work, and such rubber boots have been strengthened by extending the sole over the upper at the instep to peculiarly 'it them for sailors7 use or for the use of gardeners by protecting the uppers in such places with the additional thick 'ness ci' rubber. Suchrubber boots vare stii and unsightly, and do not protect the boot as completely as does the projection of the tap or double sole, which by extending beyond the main sole and the uppers forms a guard or fender for the sole and upper, and prevents the cutting ofthe same by any sharp or pointed material.

In order that my invention may be fully understood,l Will proceed to describe it withref erence to the accompanying drawings, in

Figure l is a side view of a rubber boot provided `with a projecting under sole or tap extending from the heel forward. 'Fig'. 2 is a view of a rubber boot provided With a projecting under sole or tap anda projection extending around the heel. Fig. 3 is a sectional View showing the projecting under sole or tap and the guard extending around thel heel.

1n the drawings, A represents the upper of the rubber boot. b is the insole, c the rag 5o sole, and d the outsole. B is the eXtra under sole or tap, and b the projection or guard, extending beyond the main sole and the heel, if desired. rj he extra sole may be made in the form of the well-known diamond tap, the point of which extends into the shank, and may be made to project beyond the sole and upper at the tread ofthe boot forward of the shank only, thus protecting the toe andthe sides of the sole and upper. The eXtra sole may extend to the heel, and thus protect the sole and upper forward of the saine, as is shown in Fig. 1, and theheel may be protected by the guard b', extending around the heel; or the extra sole may extend from end to end and project all around the main sole, thus forming a strong and durable guard for the sole and upper, and in this case the heel may be secured to the extra sole B.

A rubber boot constructed on this principle 7o not only protects the sole and upper of the boot against injury, but it gives a inuch lriner foothold to quarrynien and miners, enabling them to perform their work with more security.

I prefer to bevel the upper surface of the guard b, and extendv the roughening to the beveled edge, as is shown in Figs. 1 and 2.

Having thus described my invention, I claim- 1. A rubberboot or shoe provided lwith a tap or extra sole extending beyond the main sole, constructed to protect the boot, as de scribed. Y

2. The combination, with the upper a. and S5 sole d. ot' a rubber boot, of the eXtra sole B, provided with the projection or guard D. as described.

3. rllhe combination, with the main sole, the upper, and the heel o` a rubberboot, of the 9( extra sole B, projecting beyond the inainsole, andthe guard b', extending around the rear portion of the heel, as described.

FRANCIS FLYNN.
